To all 'whom 'i't may concern:

Be it know`n that I, EDWARD E. KILBOURN, citizen of the United States, residing Aat New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Circular-Knitting Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

My present invention relates to the art of knitting and more particularly to the class of circular knitting machines.

lt consists of an improved circular knitting machine wherein are embodied certain new constructions and combinations of parts whereby new andy desirable results are produced.

In the accompanying drawings l have illustrated one form in which l have contemplated embodying my said invention and the-same is disclosed in the following description and claims.

In the drawings, Figure 1 is a rear elevation of an automaticV knitting machine with my invention applied thereto. Fig. 2 is a viewin eleva-,tien of the left end of such machine. Fig. ifi's atop or plan view of the lever engaging the pattern cylinder. Fig. 4 is a side or end view of the same. Fig. 5 is a top view of the stationary guide coacting with said lever.

Fig. 20 is a plan view showing the relation of the cam plates to the upper cam cylinder. Fig. 21 is a like view showing relation of the cam plates to the lower cam cylinder. Figs. 22, 23 and 24: are views of the needles employed in the machine.

In the knitting of seamless hose of the open or lace work pattern, it is desirable to have open or lace Work begin below the top of the leg of the stocking so that in case of full hose, a strong hem or welt can be secured, and in both full and half hose it is desirable that a strong union at the toe may be readily and easily made. It is also desirable to knit the open or lace work on the back of the leg of the stocking, and yet be able to knit the heel and bottom of the foot and toe of the stocking of solid plain knittingand to knit solid plain knitting on the top of the foot of the stocking before reaching the toe, so that there shall be solid plain knitting on both sides of the closure near the toe of the stocking. These results I accomplish by the improvements herein set forth and l am also enabled to knit drop A stitch open work, lace work and solid plain knitting in any order or in such proportions as may be desired; to change on the back of the leg to solid plain knitting when desired without changing the work on the front of theleg of the stocking; and l am also able to knit a di'erent pattern of open or lace'work on 'the back of the leg from that on the front of the same. l can also knit tuck stitch, open lace work or solid plain knitting in any order or sequence upon the leg and can knit a dierent pattern of such various stitches upon the back from that knit upon the front of the leg of the stocking.

The features of novelty which constitute my present invention are here shown as applied to the type of automatic circular knitting machine shown and described in my former Patent, No. 669,730 granted Mar. 12, 1901 and my Patent No. 679,281

J uly' 23, 1901 and I prefer to use said deviceswhcn applied to such a machine but I desire it to be understood that lthe principle of my invention and man v of its details can be used in connection with other forms of knitting machines. l

The ,knitting machine to which my novel' features of construction are applied is pro,-

- vided with two cam cylinders, earch actuatthe needles for knitting the Fig.` 13 shows the cams of cam cylinder B.

In Fig. 11, C is the knitting cam which is fixed and immovable. The side of this cam next to the interior wall of the Vcarn cylinder is recessed to receive the sliding cam C.

This cam has a projection which extends outwardly through a slot in the cam cylinder and to this projection is secured the plate 0 which is provided with a pin c. The pin 0 is engaged by the bifurcated end of a short lever 02, see Fig. 12, pivoted to a plate a2 secured upon the upper edge of the cam cylinder. The lever c2 is provided on one side with thev cam lug c3 and has its opposite side engaged by the free end o a spring c* whose opposite end is secured to the cam ring. Onv the side of the lever c2 which is provided with the cam lug c3 is the lever Cx which is pivoted to the cam ring, or. some part rigidly connected thereto.

The free end of this lever normally restsV above the cam projection c3 and is'provided with an outwardly extending projection n". A spring c:y bears upon t-he ree end of the lever Cx and tends to press the same downward and to hold it down when in a depressed position. By pressing the lever downward, its free end engages the cam lug c3 and forces the free end of the lever c2 to the right as shown in Fig. 12 and moves the slide c and cam C to the right or to the osition shown in Fig. 11. When forced to t is position the lever C* becomes a lock holding the lever c2 and carn C in the positions shown in Figs. 11 and 12 until the lever Cx is raised to its upper position and the.

spring c tends to hold the lever against accidental displacement. The plate a2 is provided with a lug a3 to engage the lever Cx and limit its upward movement. The needles which knit the back of the leg and the heel, bottom of the foot and toe of the stocking are themselves or their jacks provided with nibs which are acted upon by the cam C of this cam cylinder. The needles he conacted upon by this cylinder are shown in Figs. 22 and 23. The nibs of these needles are of three lengths. This series of needles includes the fashioning needles l, 2a and 3 each havingy the additional nib -l whichis engaged the pickers of the machine for throwing them out of and into action in narrowing and widening. The other needles 1, 2 and 3 are employed between the tw series of fashionin'g needles. Of the needles operated -by this cam cylinder the shortest nibs normallyrest upon the ledge a. In this position the latches of the needles are below the loop upon the needle, and when the nib engages the cam C the needle is depressed but fails to cast olf by reason of the latch closing upon the loop. The nibs of the remaining needles normally rest -upon ledge a. The nibs of these needles are of two lengths, a part having nibs long enough to engage the cam C when in the position shown in Fig. 11, the others having a shorter nib which will only engage thecam C. Of

these needles those having the shorter nibs do not engage the cam C and at every revolution of the machine knit a plain stitch.

Ihe machine preferably knits with what is termed a` short lead, that is, with the thread guide but a short distance in ad- Vance ofthe knitting cam, or the knitting point. These needles take the thread at about the point :1: and are limmediately drawn downward to make thel stitch. The other, and longest nibbed needles before reaching the polnt x, when the cam C is in the posit-ion shown in Fig. 11, engage such cam and are drawn downward before the thread guide has reached the point at which such needles would normally take the thread and continue to move downward below the cams C and C, casting othe loops yif any that may be upon them. Such needles so long as cam C is in the same position, continue to engage the cam C and do not take the thread though otherwise going through the movements of knitting.

The needles having the shortest nibs and which normally rest on ledge a are at such.

height that the thread will be laid against such needles below the hook of the same on 'each revolution of the machinebut as the latch is below the loop on the needle they will not knit when depressed by the cam C. When it is desired to have such needles knit their nibs will'be raised to the level of the ledge a by the cam C2. This cam when in its depressed position willhave the apex of the same on a level with or slightly below the ledge a. When it'is desired to have these needles knit the cam C2 is raised until the apex of the cam is on a level with the ledge a. In this position the needles will be raised and the latches of the same.

brought above theloop and-threads on such needle and such vneedle will then take the 1,30

i thread at the oint w and knit a stitch lock- When the cam C is moved behind the cam C and the cam C2 is maintained in its elevated position, the machine will when revolved knitvsolid plain knitting with allthe needles actuated by the upper cam ring. en it is desired to reciprocate the cam cylinder to produce reciprocating knitting,`

another cam Cs of like construction will be raised to the level of the ledge a. This cam is raised and lowered by a lever 01 provided with a projection c, similar to the lever for operating the cam D2. A spring 012 bears upon the upper side of the lever cfm and tends to maintain it in its lower position.

The arrangement of cams in the lower cam cylinder B is simpler, for as the needles operated by this cam cylinderv do not knit during reciprocating knitting, piovision for such knitting is omitted. This cam cylinder is provided on the inside with theknitting cam D, which like the cani C of the upper cam cylinder may engage all of the needles provided with nibs for this cylinder.

As in the case of the cam cylinder A, theneedlesY of this cam cylinder are divided v into three classes having nibs ofv diiferent 'f lengths. n l

land 7, Fig. 24, having nibs of different lengths corresponding to the lengths of the These needles are shown at 5, 6

A"'ni'bs of the needles actuated by the upper -f-"oylinden The shorter nibs are normally -fra-ised. by the riser cam d to the height only ofithe ledge b. This does not raise the latches above the loops upon the needles,

and as the thread guide and cam D approach these needles the thread is laid across the needles below the hook. the cam D then depresses them butl owing to t-he latch being below the loop of the needle, the needles do not cast ofi'. The other needles are provided -with nibs of different lengths but both are raised by the riser cam to the height of the ledge b in which position the latches are abovethe needle loops. The cam D is directly below the cam C of the upper cam cylinder A and as D approaches these needles they take the thread at the same point and are Vforced downward to knit the ordinary plain stitch.

The cam Dis provided with an auxiliary l cam D bearing the same relation to the cam Dthat the cam C does to the cam C. This cam is shown in Fig. 13 in its withd2. .A lever d3 i s pivoted to the cylinder having its free end normally above the cam faced end of the slide d and said lever is provided with an outwardly extendin lug d4. A spring d5 is so connected to the sde al as to force the slide beneath the free end of the lever als, when such lever is in its raised position'. In this .position of the lever and slide the cam is in its retracted position behind cam D. By forcing the free end of the lever d2 downward it engages the cam face of the Aslide d and forces it t-o the right (see Fig. 14) and moves the cam D out from behlnd the cam D and into the position shown by dotted lines. When forced to this position the cam and lever are locked as the force of the spring d tends to niove the lever downward. In this position the cam D will engage the longer nibbed needles of the ledge b and begin to depress them before they have takenl the thread from the thread carrier. It then moves them downward and vcauses them to cast olf the loops that may be on them, thereby dropping their stitches, and while the cam D remains in this position the needles engaged do not knit.

D2 is an auxiliary riser cam which engages only the nibs of the needles which rest on ledge b', and engages these only when in a raised position. This cam is secured to a slide in a vertical guide way in the cylinder, and this slide has a projection d extending outwardly beyond the cylinder by which the cam may be raised and lowered. When this cam D2 is in its raised position, and the cam D is in its retracted position, all of the needles take the thread from the thread guide and knit a course of plain stitches at every revolution of the machine. When the cam D2 is in its lower or inoperative position the needles that are raised only to the height of ledge b are not raised high enough to bring the latch of the needle above the loop on4 the needle and the downward movement of such needle by the cam D does not cause it to cast oil its loop as the latch closes upon the thread in the hook. The needle is, however, raised so high that at every round of the thread guide a thread is laid across the needle below the hook and above the latch.

The needles of the needle cylinder are divided on a line running longitudinally of the machine into two sections. each containing about one-half of the needles of the machine. The section of the needlesl .nearest the front of the machine or that side of the same shown in Fig. l0 are provided with Y edge nibs to engage the cam construction of the lower cam cylinder B; It will thus be seen that at each rotation of the machine the cams of the cylinderA are for approximatel one-half of its revolution out of contact wit the nibs of the needles thatareactuated by it. It is during this period of Ythe revolution of this cam cylinder that the cams are moved from one position to the other.

The cams C', C2 and C3 are moved into and outof'operative position by cam plates located on stationary parts of the machine, so as to actupon said cams during the period that they are out-of engagement with the nibs of their needles. These devices are more particularly shown in Figs. 15, 17 19 and 20. In order that Ythese cam plates may act each upon its cam without affecting the others, they are mounted in different vertical planes and the pins or projections for enga 'ng with them are made of different lengt s to engage therewith.

E is a stationary rin or casin which ex tends wholly or partia ly aroun the upper cam cylinder. It extends in this instance around the needle section operated by the upper cam cylinder and a little beyond each of the section, This casing E is provided on its inn'erside ywith a ledge or flange e extending inwardly toward the cam cylinder. A cam plate e is pivoted in line with this ledge or flange and a spring e2'serv'es to normally keep it in a depressed position. The inner side of this cam plate is fiush with the inner face of the flange e. At the other end of the flange is pivoted the cam plate es. This cam plate is of half the thickness of the flange e and is so mounted that its outer side is against the inner side of the casing E, and therefore, extends inwardly only half the Width of the flange.

The cam C3 is to be operated only during reciprocating Work. The projection c to operate such cam'is of' such length that it does not engage with the cam plate e and as the cam cylinder is rotated in the direction shown by' the `arrow in Fig. 20, the projection 011 passes under the flange e. This iiange, as. will be seen, prevents the accidental sh1fting of the ca'mduring the period that the active cams of the upper cam cylinder are in engagement with their needles as during such period .the projection c is beneath the flange e.. On leaving this flange the projection c11 passes under the ,pivoted cam plate e which rises and. permits the after which the cam plate projection to pass,

is thrown down to its normal position by the spring e2. As long as this operation is continued, the cam C3 therefore remains in its depressed position.

'cam plate When reciprocating work is begun on the first movement of 'the Vcam cylinder in a direction the reverse of its regular rotation, the projection c11 engages the cam plate e and is raised upon the tlange e which holds the lever 01 and the cam C3 in their elevated positions. During this movement the cam C3 isin rear of the cam C and the needles after knitting are all raised to the level of the ledg a. As soon as the projection c leaves t e ledge e the lever 01 is depressed by the spring bearing upon the same. On the return movement the cam C3 is not needed and the projection e passes below the ledge e and cam plate e5as in circular knitting; on its next movement it is again raised by the cam plate e and held during the period that it is' required by the ledge or flange e.

The cam plate e3, ,see Fig. 17, is ri 'dly secured to its pivot and on the outsiil of theV casing E, such'pivot has the arm e* secured thereto, this arm is connected byconnections as hereafter set forth with pattern mechanism Iwhich control the positiony of the camplate and the cam C. When the arm e* is moved and the point of .the cam p late is raised, theprojectioncs of lever 0 will engage the underside of the cam plateA and the lever and cam C2 4Iwill be depressed. When, however, the arm c* is moved so that the point of the cam plate is depressed, the projection o8 engages lthe upper side of the cam plate and the lever and cam C2 are raised. The projection c8 after leaving the rests upon the ledge or ange e and the cam is thereby held in its elevated position. As the flange extends over the needles engaged by this cam the pressure of the needles upon it cannot move the lcam from its position. lWhile the projection es is passing from one end of the flange e to the other the cam is free from all pressure' which would serve to move it downward and it, therefore, remains in position. Should it be accidentally moved, however,

the cam plate e3 would again raise it before'A it would engage the needles. ciprocating work, cam plate e3 is held in position to raise the cam C2. Such cam` in case of accidental downward movement would be raised by cam plate es when moving in one direction and by cam plate e when moving in the other. In either case the cam would be heldup by the ledgeor flange e. 15 and 20 is provided for moving cam C intoA and out of operative position. This cam plate has an arm e securedto its pivot and this arm is connected with pattern mechanism by which it is controlled. When this .cam is turned and its point raised, the projection o* will engage the underside of the camv plate and the lever Cx pressed, moving the cam C into operative During re- A further cam plate e, see Figs. v

'will be deposition. When this cam plateeV is moved downward so that'the projection c* of the lever C* engages the upper side of the same, the lever CX. will be raised and the spring o4 willvdraw the cam'back into inoperative position. The projection c* is of such length 'thatthe cam plate e5 is placed out of the path of the projections whichgactuate the cams C2, C2 and therefore, the cams C3 and C2 are never `affected. thereby, and as the projection c* is in aplane above that of the projections c3 and c, cam C is not affected by the other camplates for this cyIin`der.` For controlling' the cams D and D2 of the lower cam cylinder, certain othei cam plates are provided.. The needles actuated by the lower cam cylinder occupy the opposite half of the needle cylinder from those actuated bythe upper cam cylinder, therefore, the cam plates for moving cams D and D2 are on `the opposite side of the machine from those which control the cams of the upper cylinder.

f is a cam plate for moving the cam D. This cam plate is pivoted and the pivot is provided with a crank arm by which the plate may Vhave its free end turned upward or depressed. When it is raised the projection d4 will engage the underside of the same, the lever als will be forced downward and the cam D moved into operative position, and when depressed the same projec- V tion will engage the upper side of the cam pla-te and lever d3 will be raised permitting the spring d5 to withdraw cam D from operative position.

An inwardly extending ilange or ledge-F is formed on the inner side of the ring or casing wholly or partially surrounding the lower cam cylinder. This flange extends around the needles actuated by the lower cam cylinder, and the cam plate f is located about midway between the ends of this flange, and thus moves cani D when the cams of the cylinder are out of Contact with the nibs of their needles. The cam plate f is employed to move the cam D2. This is shown at the left in Fig. 2l with its free end extending toward4 cam plate f while the other Veind is pivoted close to the end of flange F atthat side of the machine. The pivot of this cam plate f is also provided with a crank arm by which the cam plate may have its free end moved upward or depressed. `When it is depressed the projection d6 of cam D2 will engage the upper side of the cam plate and the cam will be raised into operative position` and when the free end of the cam plate f is raised, the said projection will engage the underside of the cam lplate and the cam will be depressed. j l

The cam plate f is placed farther away from the cam cylinder than cam plate f, and is in line with the ledge or flange F. `When instrumentalities.

raised. upon the ledge F and the cam is held 1n its upper or operative position,

around the half circle of needles controlled by the lower cam cylinder. The projection d* for operating the cam D is of such length that it will not engage with the cam plate f or with the ledge or flange F. The projection d6 being longer than the projection d4 may sometimes come in contact with the cam plate f, but as/the cylinder moves in the direction of thearrow in Fig. 21, it will afterward come into engagement with the cam plate f and be put in proper position thereby, before Ait reaches the needles of the cylinder.

Tt will thus be seen that it is only necessary to provide pattern mechanism to control the cam plates' e3, e5, f and fto effect such movements ofthe cams in the two cam cylinders `as will producev the pattern of work desired. Tn the present instance, these cam plates are controlled by the following As shown in F ig. 1 the machinenear one end is provided with a pattern cylinder G which cylinder is mounted on a shaft Gr, extending transversely of the machine. The pattern cylin-y der is provided at its outer end with the ratchet G2 by which it is revolved, through pawl g. This pawl has its upper end hooked and engages a cam or eccentric y" on `the transverse shaft J through which motion isl'conveyed to the cam cylinder and is caused to have one reciprocation and move the pattern cylinder the distance of one tooth of the ratchet at each revolution of the cam cylinders. This pattern cylinder is provided with a spiral groove extending from one Aend to the other of the cylinder and in such groove, the cylinder is provided with holes g to receive pins g2.

A bracket G3 is secured to the left end of the frame of the machine, see Figs. 2, 7 and 9. This bracket supports a rod Grt rigidly secured to said bracket. A lever G5 pro- -vided withan elongated hub g3 is vpivoted upon the rod G4 so that it is free to swing and slide upon said rod. The free end of the lever has a downwardly extending pro jection of such width as to enter the groove of the pattern cylinder. The free end of the lever G5 is extended laterally in both directions and at each end is provided with an upwardly extending ear in which is rig idly mounted a rod 9*. A rock shaft T is mounted in bearings and extends longitudinally 'of the machine. This rockshaft is provided with an arm i extending outward or rearwardly from the machine. A link I has is upper end pivotally connected with the outer end of the arm z', and its lower end is provided with an aperture through which the rod g4 passes freely. The link l engages the slot of the slotted guide L2 through lll@ 'rock shaft is provided with a spring z" (see Fig. l) which tends to turn said shaft in a direction to maintain the-projection of thev lever Grs down upon thebottom of the groove of the, pattern cylinder or upon the top of pins g2 in such oove. The rock shaft I is also provided with an upwardly extending arm z2. The upper end of this arm is provided with an aperture through which passes a rod I2 which is connected with the crank arm of cam plate f for controlling cam D2. As the spring z" tends to turn the shaft I, so as to move the arm i2 outward, such action tends to draw the rod I2 outwardly and maintain the cam plate with its free end depressed a-nd keep the cam D2 in its operative position. When thedownwardly extending projection of the arm Gs is enga ed biy a pin g2 the arm is raised and throng link I.

arm i, rock shaft I, arm '2 and rod I2 the freev end of the cam plate will be raised and the cam D2 depressed into inoperative position.

As before stated, the cams of the lower cam cylinder co erateonly with one-half of the needles o the needle cylinder, the needles on the front half of the stocking. In order to effect a like control of the cam plate es Yfor moving cam C2 of the upper cam cylinder, a rod K2 is pivotally connected with the crank arm /e of the cam plate e -which extends rearwardly and passes through an aperture in the upper end of an arm or lever K pivotally mounted on a rock shaft K, mounted on the same side of the machine and parallel with shaft I. To this lever K is pivoted the bell crank lever la, providedwith the shoulder k. The outer end of the bell crank lever 7c normally restson the upper end of an arm s rigidly connected with the rcck shaft I. The cam plate ea is normally heldfin its depressed position by a spring e. When the rock shaft I is turnedto effect the raising of the free end of the cam platev f the arm is engiages projection lc on the bell crank lever an the lever K' is moved inward moving the rod K2 and raising the free end of the cam plate e. When the arm G5 passes olf from one of the pins g2 and the arm drops .to the bottom of the groove of the pattern cylinder the spring z' retracts the rod I2 while the spring e moves the rod K2 and the leved K outwardly, the free ends ofthe cam lates will thus be depressed and 'the cams 2 and 'C2 raised to operative position.

When it is desired to ermit the cam D2 tov act independently of t e cam C2, the bell crank lever lc is raised out of contact with the arm i2. Toaccomplish this lthe shaft K is provided withan arm k2 so placed on said shaft that the outward movement of the arm k2 will engage the depending arm of the bell crank lever k and raise the other arm of such lever so vthat its projection lc will not be engaged by the arm is of the shaft I; This movement of the shaft K and its arm k2 is in this instance effected by a pattern wheel H on the op osite or front side of the machine. The sha G on which the pattern cylinder is mounted extends across the machine from rear to front and at its Jront end is provided with a pinion gx which meshes with a ear wheel H connected to and moving wit 1 the pattern wheel H (see Fig. 7

The relative sizes of the pinion and gear are such that the projection of the lever Gr5 will traverse the entire length of the groove in the periphery of the pattern cylinder dur- -ing the knitting of a single stocking and the pattern wheel will during the. same time, make one complete revolution.

The shaft K extends beyond the left end of the machine and is there provided with a crank arm k3. This crank arm is connected by a link c with an arm Z extending outwardly from a shaft L which is moiuited in bearings transversely of the machine and this shaft has a downwardly extending arm l lying in the plane 'of the tread z of the pattern wheel, so that the arm l will be engaged by risers on the said tread. The tread h of the pattern wheel is,- therefore, provided with a riser for engagin the arm Z at the point at which it 1s desired to have the cam C2 raised, and to have the cam act independently of the cam D2 of the lower cam cylinder and this riser is made long enough to continue this operation for such period as is desired.

Upon an outwardly extending iiange ot the casing surrounding the lower cam cylinder is mounted the curved slide F. In shape it conforms to the flange upon which it is mounted and it is sustained upon the fiange by two screws passing through` two slots f* fx in said slide. The slide is thus mounted for a movement to the extent of the slots. This slide extends approximately half way around the cylinder and to the end near the front of the machine is secured the depending arm or bracket f2, the lower end of which extends inwardly and is operatively connected'with the crank arm of the cam plate f. A spring f3 is connected withl this sli de and tends to draw the same toward the rear of the machine, in which position the cam plate f is depressed and the arm d3 maintained in its elevated position, allowing the spring d to draw the earn D into its recess behind cam D, and consequently out of operative position. The rearward end of the slide is rovided with-an yolutwardly extending projection f4, and it willebe at once seen that when pressure is applied thereto in the direction. of the arrow 1n.; Fig. 18 the crank arm of the cam plate f will be raised and the lever d8 willbe depressed on the next revolution of the machine. The movevment of this slide is eHected at the proper .m on the shaft M, which gives mot-ion to the cam cylinders. This disk is similar to a disk shown in the Patent No. 669,730v hereinbefore referred to.l This'disk'has a circular dange extending upwardly from the upper .side of the disk. Apart of this flange is hinged to open outwardly, forming a gate and is normally closed by a spring. A web\ extends from the hub of the disk to the gate, of such shape as to act as a caln tol force anything coming in cont-act therewith out V`4Jthrough the gate.

The spring f3 drawing the slide l1" toward the rear of the machine forces the projection f4 against the inwardly extending end o-r arm of the lever F2 and turns the rod or shaft lf3 so as to bring the free end of the arm f8. and pin f above the disk m.

The rod or shaft F3 is maintained in its uppermost position 'by the arm flo of a rock shaft F4, the rod F3 resting upon the flattened outer end of said arm. The rock shaft lt is mounted transversely of the machine above the bed of the same and has an arm f at its opposite end. rllhis arm is connected by a link f with a bell crank lever which has its other arm bearing against the initier edge of the ring or annulus H2 onl the pattern wheel H. rlhe weight of the rod and the parts connected therewith serves to keep the free arm of the bell crank lever E against the inner side of the ring H2. Risers of such extent as may be desired may be' secured to the inner side of this ring. So long as a riserbears upon the free end of the bell crank lever the rod or shaft F3 will be held in its uppermostposition as shown in Fig., 6, but when such riser'moves out from under t-he arm of the bell crank lever, the weight of rod or shaft F3 will force down the arm flo and this will cause the-pin fg to drop down within the flange of the disk m. As the shaft M revolves the web within the flange will be brought into contact with the pin fs and the same will be forced ont through the gate to the outside of the disk. This action turns the rod or shaft F3 causing the arm f7 to draw upon 'the lever Fz-and move the slide F so as to elevate the free end of the cam plate f and sition. So long as the bell crank lever F5 the cam D will remain in ,to receive risers h.

is unaffected by a riser upon `the ring Hz y n operation, but as soon as it again engages a riser the rod or shaft F? will be raised and the spring f3 will restore the' parts to the position shown in Fig. 6.

A rod-E is connected to the crank arm es of the cam plate e5. This rod passes through an aperture in the end of an arm 61 projecting from a frame or bracket E2 that is pivotally'mounted on the upright rod or shaft F". ZAf lever e is .pivoted to the bracket E2., One end-of thislever is provided with 'the upwardly extending pin e and a spring e is connected with said bracket ,inl such a Way as to tend to throw the end of the lever c provided with thepin e toward the shaft M and heneath't-he disk m. This disk has the lower side of the same constructedwith the dange, gate and ycam web corresponding to the .several parts on the upper side of the disk'. YThe other end of the lever e12 is connected by a' link ES with an arm E*l 'which is connected to one end of therock shaft E mo-untedin much the same manner as rock shaft Ft and in close proximity thereto. rlhe other end of the shaft Exs is provided with the crank arm 6.14 and this crank arm is connected by a link E6 to one 95 arm'of the bell crank lever ET. rlhe other arm of the hell crank lever is in position to engage the inner face of a ring Hsof the pattern wheel H. This ring is constructed The shaft E5 is provided with the spiral 4spring e (see Fig'. 2) which is connected with the shaft E5 in such a way that it tends to force the bell crank lever E7 into contact with ,the ring HB' or its risers, and to throw the free end of lever eMl upward so as to bring the pin e (within the downwardly extending flange of the wheel m. So long as the bell crank lever E7 engages a riser on the inside of the ring H3, the free end of the lever 612 is be vlow the disk m and is maintainedin a position near the shaft M by the spring acting on the bracket E2, but when the bell crank lever E? passes from a riser or risers on the ring H3 and moves against the inner side of said ring the spring upon the rock shaft'E moves the shaft to cause the arm E* to draw down one end of the lever e and raise its opposite end 'bringing the pin @1B within the ange on the lower side of the disk m. rfhe rotation of that disk brings the pin at the proper time within the operation of the web and gate and the pin 613 is' forced outward swinging the bracket E2 and causing its arm el to move the rod E2 and raise the free end of the cam plate e5. So long as the bell crank lever E7 remains in this position the cam plate e5 will be in the raised position and the projection o? of the lever 0 will engage the under side of`
